研究了Ｃｙａｎｅｘ９２３在正庚烷溶液中对１５种稀土元素硝酸盐的卒取，计算了分离系数，得出了反应机理，考察了温度对萃取平衡的影响以及萃合物的红外光谱，发现Ｃｙａｎｅｘ９２３有可能应用于从轻稀土中分离镧以及从重稀土中分离钇。
Cyanex923 in n-heptane solution of 15 kinds of rare earth nitrate nitrate extraction, calculated the separation factor, the reaction mechanism was investigated, the effect of temperature on the extraction balance as well as the infrared spectra of the extract, found that Cyanex923 It may be applied to the separation of lanthanum from light rare earths and the separation of yttrium from heavy rare earths.
